Examples of org.jboss.netty.channel.ChannelHandlerContext

org.jboss.netty.channel.ChannelHandlerContext
Provides the properties and operations which are specific to the {@link ChannelHandler} and the {@link ChannelPipeline} it belongs to.Via a {@link ChannelHandlerContext}, a {@link ChannelHandler} can sendan upstream or downstream {@link ChannelEvent} to the next or previous{@link ChannelHandler} in the {@link ChannelPipeline}.
